M ETALLI Q ROOFING.

SPECIFICATION forming part of Letters Patent No. 425,830, dated April15, 1890.

Application filed January 24, 1890. Serial No. 337,952. (No model.)

To all whom it may concern:

Be it known that I, LoNeLEY LEwIs SAGEN- simple and effective means foruniting r each side of said openings.

locking together the sides of metallic roofingsheets, the means employedbeing such as that the roofing-sheets may be rolled in a compact formfor shipment and the seam-cap formed after having arrived at itsdestination, as will more fully hereinafter appear.

In the accompanying drawings, Figure 1 is a plan View of the endportionof a roofingsheet, showing the position of the cleat-openings before theside flange and cap-seam are formed, the dotted lines indicating Wherethe bends are made in the sheet to form said side flange and cap. Fig. 2is a View similar to Fig. 1, showing the preferred form of cleat inposition in the cleat-openings, in which position the roofing-sheets maybe rolled for.

shipment if desired. Fig. 3 is a perspective View of the end portions oftwo roofing-sheets as placed together before the seam-cap is formed, thedotted lines indicating where the bend will be to form said cap. Fig. 4is an end View of a roofing-sheet having the side flange and seam-capformed with a cleat in position in said cap. Fig. 5 is a perspectiveView of two roofing-sheets in position to be locked, the View beingtaken from the reverse side of that shown in Fig. 3; and Fig. 6 is asimilar View with a portion of the seamcap folded to place. Fig. 7 is across-section through the standing seam, taken between the cleats; andFig. 8 is a similar view taken through said seam and one of the cleats.

My invention consists in forming near the outer edge of theroofing-sheet and on that side from which the overlapping seam-cap Awill be formed the cleat-openings a, into which the end portion b of thecleat B rests, as shown, the shoulders I) of the cleat resting againstthe metal of the roofing-sheet at The cleat-openings are formed,preferal'ily, before the seamcap A. is bent, and the tongues 19 of thecleats B are then put to place, as shown in Fig. 2, in which positionthe roofing-sheet may .be rolled in a compact form for shipment with thecleats in position.

' The seam-cap A and flange G of each roofing-sheet may be'bent andformed in the factory before shipment, as shown in Fig. 4, or afterhaving been put to place 011 the roof, as shown in Figs. 3, 5, and 6. Ineither case the cleats B are bent and formed with the seamcap A afterthe tongue I) of each cleat has been put to place, as shown in Fig. 2.It will be seen that the shoulders I) of each cleat fit up against theroofing-sheet at each side the cleat-openings a, and that the apex bendof the seam-cap A is formed on a plane below the cleat-openings, (beforebending,) as shown in Figs. 3, 5, and 6, and when bent to positiontheapex of this seam-cap A is on a plane above said openings, as shownin Fig. 4, in which position the shoulders I) of each cleat are bentbelow the apex of the seam-cap.

The object in having the seam-cap and cleat bent in such a manner asthat the shoulders b of each cleat when bent will fall below the apexplane of the cap is that the cap cannot be elevated to slip or becomeloosened from the cleatthat is, aft-er the cleat is thus bent and nailedto the sheeting the cap A cannot be elevated, on account of theshoulders formed on each cleat on the inside of the seam-cap.

My invention is applied as follows: Vhen the vertical flange O andsea1n-oap A are formed before leaving the factory, as shown in Fig. 4c,the cleats B are nailed to the sheeting, and the flange C of theadjacent sheet is then put to place between the upward and downward bentportions of the cap, the body portion of said adjacent sheet resting onthe cleats, in which position the seam-cap and cleats are compressed orpinched together with suitable tools, as shown in Figs. 7 and 8. Whenthus united, it is impossible for the wind to blow off or loosen theroofing-sheets, for the reason that any upward tendency of the cap A isprevented by reason of the shoulders b on the cleats B. When the sheetsand cleats are shipped in a roll and the flanges and seam-caps formed onthe roof, as shown in Figs. 3, 5, and 6, the cleats are first bent gagcdfrom said cleats, and at the sametime admit of ample expansion andcontraction.

The seam-cap thus formed is freeof any over-. lapping outsidecleats,which is a great advan-. tage, as all outside cleats are liableto rust or.

cause the cap-seam at those points to rust and I leak. The seam-cap,being free of any overlapping cleats, presents a neater appearance 1 andwill last longer. The cleats, being protected by the seam-cap, will lastmuch longer, which renders the connection between the roofing-sheetsmore secure. A portion of surface metal is dispensed with, lessening thecost of manufacture. The cleats, being bent with the seam-cap, enablethe roof to be ap-; I

plied quickly and economically.

' What I claim as new, and desire to secure by Letters Patent, is-

1. The means herein shown and described for connecting and anchoringmetallic roofingplates to the sheeting, consisting of a slot formed inthe downward extension of the seam-cap and a shouldered cleat, thenarrow tongue portion of said cleat restingin said slot and theshoulders of said cleat resting against the roofing-sheet at each sideof the said slot as and for the purposes set forth.

2. A metallic roofing-sheet having at one side the vertical flange. Oand at the other sidethe seam-cap A, the latter having a slot at in itsdownward extension, in combination with a shouldered cleat B, the tongueportion b of said cleat resting in said slot, the shouldered portions 12b of said cleat resting against said cap-seam at each side of said sloton the under surface of said cap, as set forth.

3. The metallic roofing-cleat B, having the narrow tongue extension I)and shoulders I) b, said cleat being so bent and formed as that saidshoulders will fall below the apex bend thereof, as and for the purposesset forth.
